SIEGIFICATION forming part of Letters Patent No. 629,057, dated July 18,1899.

Application filed April 19, 1899.

To all whom it mcty concern:

Be it known that we, WILLIs 0. WESLEY and WILLIAM CLARK, citizens of theUnited- States, residing at West Superior, in the county of Douglas andState of Wisconsin, have invented certain new and useful Improvements inThill-Oouplings; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same'..

The invention has relation to thill-couplings of the 'antirattler type;and the object is to provide a device of this character which shall besimple in constr uction, d urable in use, comparatively inexpensive ofproduction, and one in which the thills may be easily and quicklyattached to and removedtherefrom.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter moreparticularly described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of ourimproved thill-coup ling, showing in full lines the position thepartsassume when in operation and dotted lines the position they assume whenit is desired to disconnect the thills froni the vehicle. Fig. 2 is anenlarged detail perspective View of the coupling-head. Fig. 3 is asimilar 'view of the thill-iron, and Fig. 4 is a similar View of theelastic noiseless cushion.

In the drawings, 1 denotes the axle; 2, the axle-clip; 3, the coupling;4, the thill-iron, and 5 the elastic cushion. p

The coupling-head is secured to the axle 1 by the clip 2 and is providedwith a transverse oval aperture 6, intersected by a vertical transverseslot 7, one wall o'f-which is'ex tended upwardly to form a stop-shoulder'8, for a purpose hereinafter to appear.. I

The elastic cushion, which is preferably made of rubber, has itsexternal outline corresponding in shape to the oval aperture 6, withinwhich it is seated, and is provided. with the slot 9, registering withthe slot 7 of the coupling-head.

The thill-iron has near its rear end a rectangular aperture 10, across-bar 11, and latorally-projecting arms orextensions 12. I

In assembling the parts .the elastic cushion Serial No. 713,578. (Nomodel.)

5 is inserted sidewise into the aperture 6,with its slot 9 registeringwith the slot 7 in the coupling-head. The thill-iron is now engaged withthe coupling-head, with the arms 12 of the thill-iron straddling thehead or paralleling the sides thereof. The thill-iron is now elevateduntil the cross-bar 11 contacts with the stop 8, which guides the bar 11through the slot 7 of the head and into the slotof the elastic cushion.The thill-iron is now lowered in the position shown in full lines inFig. 1. o

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring an extended explanation.seen that no parts of the metal contact, but

are all spaced apart by the elastic cushion,

It will be walls of the aperture and the inner faces of the arms. Itwill be further seen that the arms serve to preventthe cushion fromWorkwhat we .claim, and desire to secure by Letters Patent, is-

Athill-coupling, comprising a headformed with a transverse elongatedaperture 6 intersected by the transverse slot 7, the rear wall of whichprojects upwardly to form a stopshoulder 8, an elastic cushioncorresponding in outline to, the aforesaid aperture, and pro vided withthetransverse slot registering with the slot of the head, and thethill-iron having'a rectangular aperture 10 and cross-bar 11 at the endof the aperture, and parallel rearwardly-extendiing arms 12,substantially asset forth. v

In testimony whereof we have hereunto set our hands in presence of twosubscribing witguesses.
